To all whom it mag concern:

Bea known that I, BENJamnWoon, a citize of the United States, residing at New ork, in the county of New York and State j of New York, have invented a new and useful .Matrix-Scorcher, of which the following is a specification. This invention relates to a matrix scorcher for drying a stereotype matrix in curved form.

The device is used rincipally in connection with the so-cal ed dry process of for inggiatrices, wherein the fiong used in ma ing t e matrix contains a small ercentage of moisture which, after theme. rix has been molded, must be eliminated from the same.

In the old or wet process the sheet, together with the type upon which it is pressed, is placed in a steam heate press and there remains until the type is thoroughly heated and the matrix becomes sufliciently dry to be removed from the type. In the dry process the sheet is immediately removed from the type after the impression has been made, and it is only necessary to dry out or scorch the slightly dampened sheet before placing the same in the stereotype mold. It is extremely desirable in this dry process to have the scorching done when the matrix is substantially in the curved form as, if the matrix is scorched when flat and is thereafter curved, cracks in its face are apt to develop.

The object of my invention is to improve the construction of machines for thus drying the matrix sheets in curved form, to increase their efiiciency, and to cheapen and simplify their manufacture.

With this object in view the invention consists in certain devices. arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings, in which- Figure 1 is an end elevation of my device looking in the direction of the arrow 1 in Fig. 3: Fig. 2 is a vertical transverse section of the machine taken on the line 2-'2 in Fig. 3; Fig. 3 is a side elevation of the device shown in Fig. 1 but showing the cover in closed position; and Fig. 4 is a detail sectional view showing the manner of securing certain of the parts to the end castings.

comprises essentially a curved supporting plate 10 rigidly secured to a pair of substantially semi-circular end castings 11 and 12. Secured to the plate 10 as by hinges 13, is a curved cover plate 14: provided with a handle 15 and so formed as to closely clamp the matrix plate upon thecurved supporting plate 10 when in closed position. The cover ll is provided with a plurality perforations 16 through which steam and moistair may esca e from the matrix, which is designat d, by he reference letter A in Mounted within the supporting plate 10 and concentric therewith is a bailie plate 17 also provided with a plurality of perforations 18 and secured by screws 19 to flanges on the end castings 11 and 12 in spacedrehu tion to the plate 10. Extending longitudinally through the machine and secured in lugs 20 in the end castings is a plurality of perforated burner tubes 21. As shown in Fig. 2 the two upper tubes are provided with a single longitudinal row of perforations, while the four lower and intermediate tubes are each provided with two rows of perforations, this arrangement resulting in a more even distribution of heat over the supporting plate. Each of the tubes 21 is provided with an air inlet or mixing device 22 and with a regulating'valve 23. All of the tubes are connected by suitable fittings with a supply pipe 24 provided with a regulating valve 25. I

The operation of the device will be evident from the preceding description, but a brief summary of the same may be of value. The operator upon receiving the matrix plate from the impression roller 10 and closes the perforated cover thereon, thereby clamping the plate in curved position. The end castings are provided with openings 26 through which the gas issuing from the various burner tubes may be easily ignited. The valves 23 serve to regulate the supply of gas to each tube and the valve 25 afiords means by which the .supply of fuel may be stopped without disturbing the adjustment of the several valves 23. The baflle plate 17 prevents the direct contact I The machine illustrated in the drawingsplaces the same upon the supporting plate of the jets issuing from the perforations in the tubes 21 with the supporting plate and thus provides a more even distribution of the heat thereto.

1 do not Wish to be limited to the precise details disclosed. herein. as it is evident that various modifications may he made Within the scope of m invention by those skilled in the art, hut

What l do claim is A. matrix scorcher comprising a substantially semi-circular supporting plat/e a curved clamping cover secured thereto, and a plurality of fuel burners mounted at substantially equal distances from the inner surface of said supporting plate. said burners having openings therein so proportioned in capacity as to provide substantially uniform heat distribution for said supporting plate.

2. A matrix scorcher comprising seinicircular end castings, a curved supporting plate secured thereto, a curved clamping cover hinged to said supporting plate and a. plurality of fuel burners extending through said castings and Within said plate.

A rnatriir scorcher comprising a curved supporting plate heating said plate and a curved perforated loafille plate concentric With said supporting plate and acting to more evenly distribute heat thereto.

4:. A. matrix scorcher comprising end castings, a curved supporting plate secured thereto, flanges on. said castings, a heme plate secured to said flanges concentric with said supporting plate but spaced therefrom, and heating means for said plates.

5. ii. inatriir scorcher comprising semicircular end castings, a curved supporting plate secured thereto, a perforated clamping cover hinged to said plate, a perforated hadie plate secured to said end castings concentric with said supporting plate, .and a plurality of burner tuloes extending through said end castings and secured therein, said tubes being provided with perforations arranged longitudinally thereof, and being all connected at one end with a single fuel supply pipe.

lln testimony whereof l have hereunto set my hand, in the presence of two suhscrihing witnesses.
